Best decision ever- when realisation hits

Today I finally realised that leaving almost 2 years ago was the best decision I could have ever made. My ex is currently having our kids at my house because he is not in the position to have them in his own home. I got home today from my boyfriends house (I go there to ensure they get quality time with their dad) there's food all over the floor, dishes stacked in the sink, the kids are still in their pyjamas or what they were wearing yesterday. My house was spotless when I left. I asked him to do his dishes before he went and he laughed at me. I reminded him that I'm not his slave and he responded no You're the kids slave. I'm not their slave either. He is a complete arsehole and thinks I'm still going to be cleaning up after him. Yes I have to do the dishes, yes I'll have to vacuum the floor because I can't just leave it there. I realise how lucky I am to have gotten out when I did. And that I have found a man who can actually look after himself these days. I wonder how my ex is going to feel when I eventually take our kids and move over an hour away from him to a place with a Man who treats me like a queen. Who does dishes and vacuums, who wants me to be happy and tells me how beautiful I am on a regular basis. I have found someone who treats me like I deserve to be treated and I know I'm worth it. How can I make my douche bag of an ex realise that he's being a dick by not respecting my home. By expecting me to clean up after our kids when it's he who had them. Yes it's my home but doing dishes and vacuuming a floor are 2 really simple tasks that one should be doing especially if they are using a space because they can't supply their own. Do I just roll with it until he can supply his own space again. I realise there is no point in getting angry because that's what he wants. It just makes me mad that I have let him into my space and he still shows so much disrespect towards me.
